I recently replaced the LED on my Fenix HL25 headlamp because the original was too green for me. I went with an XP-G2, 5700K and it also was too green. When I had that LED on a star on my metal work bench reflecting off of the ceiling with another reflector, you could see the hot spot as very white and the corona around it kind of greenish. I think its kind of normal to have a greenish corona with a more white hotspot, but I don't know why.
When I put this LED into the HL25, I'm assuming its the floody nature of the reflector that averages in the greenish corona into the overall beam. When I went to an XP-G2 6000k, the green diminished greatly. Now I'm thinking that if I want to eliminate green, I have to go with more cool white or I have to go to 5000k or lower.
I also had an XP-L, V3, 5700k LED and so I put that in the HL25 and also have a slight greenish tint. But that same LED with a different reflector exhibited a very white hot spot and slightly greenish corona. So for the time being, I'm steering away from 5700k LEDs when used with floody reflectors. I'm thinking that range of color temperature may come with more greenish corona. This is something new to me and wondering if others have seen this.
By the way that XP-L, V3 gave me nearly 20% increase in output over the XP-G2, R5 and the beam profile remains the same (or at least I couldn't tell the difference).
